Where to Buy Melanotan II Research Grade: A Supplier Verification Guide

Introduction

Melanotan II (MT-2) is a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH) that acts as a non-selective melanocortin receptor agonist. It has been studied extensively in preclinical models for its effects on pigmentation, sexual function, appetite regulation, and energy homeostasis via the melanocortin system.

Melanotan II's Research Applications

MT-2 binds to melanocortin receptors MC1R, MC3R, MC4R, and MC5R with varying affinity. Research has focused on: melanogenesis and UV-independent pigmentation (MC1R); sexual arousal in animal models (MC4R); appetite suppression and energy expenditure (MC3R/MC4R); and anti-inflammatory signaling.

Purity and Documentation Standards

Research-grade Melanotan II should meet: Purity ≥98% by HPLC; identity confirmed by mass spectrometry (MW: 1024.18 Da); sequence confirmation (Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2); and independent COA from an accredited third-party laboratory.

Distinguishing MT-2 from PT-141

PT-141 (bremelanotide) is a metabolite of MT-2 that lacks the lactam bridge and has a different receptor binding profile. If your research protocol specifically requires the cyclic structure of MT-2, confirm the product identity by mass spectrometry before use. See our PT-141 vs Melanotan II comparison.
